Einstein Rings.

So what are Einstein rings?  According to Wikipedia and Einstein ring is “the deformation of the light from a source (such as a galaxy or star) into a ring through gravitational lensing of the source’s light by an object with an extremely large mass (such as another galaxy, or a black hole)”


The graphic above will make the definition a little easier to understand.  Basically, when everything is aligned correctly, the light that we see from certain object that pass around large gravity wells gets distorted into a ring.

This is kind of like an eclipse, but instead of blocking the light, the light is bent around an object.

Of course, Hubble has found a lot of these objects that were once only speculated by Einstein’s general theory of relativity.

\theta_E = \sqrt{\frac{4GM}{c^2}\;\frac{d_{LS}}{d_L d_S}},

Of course my math skills probably aren’t up to the task anymore.   Where did I put my physics books….
